Multiple copy pad



Filed May 19, 1937 Patented Nov. 7, 1939 UNITED STATES PATENT OFFICE 1 Claim.

- This invention relates to multiple copy pads such, for example, as are customarily used in making a plurality of copies of a record, invoice, order, etc.

In accordance with a conventional practice in making a plurality of copies simultaneously with the original, the typist usually assembles the necessary number of blanks with interposed sheets of carbon paper and inserts the assem blage into the typewriter. It is not only time consuming to assemble the sheets and carbons prior to typing and later to separate the carbons from the typed copies, but it is also an extremely dimcult task accurately to insert the assemblage so that the sheets are in proper alignment, particularly when the sheets consist of printed forms whose blanks must necessarily accurately register with those of the original.

The principal objects of the present invention are to overcome the aforementioned difliculties and to provide a pad wherein the transfer or carbon sheets are so disposed that they may be quickly separated from the body of filled-in blanks or copies.

Further objects will be apparent from a consideration of the following description and the accompanying drawing, wherein:

Fig. 1 is a top plan view of a multiple copy pad made in accordance with the present invention;

Fig. 2 is a top plan view of the pad illustrated in Fig. 1, but showing the top sheet removed; and

Fig. 3 is an isometric view illustrating the manner of separating the carbons from the copies.

The embodiment chosen for illustration comprises a block of paper having sheets I which may consist of printed forms, as indicated in Fig. 1, and alternately disposed sheets 2 (Fig. 2) which consist of a suitable transfer material, such as a piece of tissue having on its undersurface a carbon coating 4.

The upper edge of each of the transfer sheets 2 is formed with a recess preferably having a depth of the order of one inch, here shown as a V-shaped notch 5 which extends between points spaced from the lateral edges of the sheet, as shown more clearly in Fig. 2. The lower end 6 of each of the transfer sheets extends beyond the lower ends of the sheets I, so as to provide a readily accessible grip, the utility of which is hereinafter pointed out, and one of the lower corners of the projecting end of the transfer sheets is preferably cut at an angle, as indicated at 8, so as to expose the corresponding corners of the printed forms I.

Although the carbon coating 4 may be coextensive with the undersurface of the transfer sheets, I preferably confine the coating to an 8 area between the line II spaced from the upper edge of each sheet to a line I2 corresponding substantially to the lower edges of the sheets I, thus leaving the projecting ends 6 uncoated so that they may be gripped without soiling the 10 fingers.

The printed forms I and interposed transfer sheets 2 are superposed to form a block or pad, and the upper edges of the sheets secured together in any suitable manner as, for example, by a w coating of latex or binding II] which is preferably confined to the areas adjacent to the corners, as shown in Fig. '1. This arrangement not only permits ready separation of the individual sheets, but is also effective temporarily to hold together two or more sheets torn from the block. Since the cut-ofi corners of the transfer sheets expose the corners of the printed forms or blanks I, collating is greatly facilitated, and hence in using a block or pad made in accordance with an the present invention the requisite number of sheets I, together with the interposed transfer sheets 2, may be quickly counted and readily torn off as a unit from the remainder of the block. As the separated sheets are temporarily co secured together by a part of the binding Ill adhering to their upper edges, there is little or no danger of the sheets accidentally separating or getting out of proper alignment, as otherwise would be quite apt to happen when inserted in 35 a typewriter. Consequently, the location of the characters on the carbon copies, whether typed in or otherwise applied, will conform precisely with the location of those on the original.

In order to separate the original and carbon 40 copies from the transfer sheets the upper marginal edge of the assemblage (the area corresponding to the recessed portion 5) is grasped by the thumb and fingers of one hand and the projecting ends 6 of the transfer sheets are similarly grasped by the other .iand, as illustrated in Fig. 3, and by a simple pull theoriginal and carbon copies, as a body, are quickly separated from the transfer sheets or carbon papers. The carbons may then be discarded or put aside for subsequent use in any of the various ways in which ordinary carbon paper is used.

It is apparent from the foregoing that a multiple-copy pad made in accordance with the present invention not only dispenses with the tedious and time consuming steps of assembling and separating the individual blanks and carbons, but also overcomes inaccuracies resulting from misalignment of the assembled sheets. Accordingly, the use of my improved pads results in a greatly increased eihciency and the elimination of considerable waste.

While I have shown and described one desirable embodiment of the invention, it is to be understood that this disclosure is for the purpose of illustration and that various changes in shape, proportion and arrangement of parts, as well as the substitution of equivalent elements for those herein shown and described, may be made without departing from the spirit and scope of the invention as set forth in the appended claim.

I claim:

A multiple copy pad comprising a plurality of superposed sheets, alternate sheets having elongate .centrally disposed recesses in their upper edges, the outer ends of the recesses being slightly spaced from the lateral edges of said sheets, the opposite ends of said alternate sheets extending beyond the corresponding ends of the other sheets, said alternate sheets having a coating of transfer material substantially coextensive with the surface of said other sheets, and binding means for securing the upper edges of said sheets together, said binding means being confined to the relatively narrow zones along said upper edges between the corners of said sheets and said outer ends or the recesses in said alternate sheets, thereby to insure ready separation 01' one or more sheets from the remainder of the pad.
